Abstract

The invention provides a spatial association rule mining method and device, electronic equipment and a computer readable storage medium. The mining method comprises the following steps: processing land change information and shoreline change information to generate a plurality of combined grid units and shoreline change intensity; establishing a model operation decision table based on the plurality of combined grid units and the shoreline change intensity; and mining the model operation decision table to obtain a spatial association rule. The step for processing the land change information andthe shoreline change information to generate the plurality of combined grid units and the shoreline change intensity comprises the processes of carrying out fan-ring-shaped grid division on the landchange information to generate a plurality of sample grid units, and determining the land change intensity of each sample grid unit in the plurality of sample grid units.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a method for mining spatial association rules, a device for mining spatial association rules, electronic equipment, and a computer-readable storage medium. Background technique [0002] Aiming at the impact of the development of shipping on the spatial development and utilization model, there is a research method based on the association rule-based spatial sequence model of coastal land use in the prior art. Adjacent lines to obtain the sort order of land types in various land and sea orientations. However, the above-mentioned research methods in the prior art actually have some limitations to be further improved, as follows: [0003] 1) First of all, because the existing methods mainly focus on the static status of land use types, they only focus on mining the order of land types in the sea-land direction in coastal areas at a certain point in time, and cannot re...
